Many elderly dread the prospect that chronic medical issues will force them to leave their homes for an assisted living facility or nursing home, making them dependent upon others for their care and personal needs. Sometime in the near future, however, new technology could help them remain in their homes longer, perhaps indefinitely, without having to give up their independence.

"Our goal is to keep people in their private homes for as long as possible," says Marjorie Skubic, professor of electrical and computer engineering at the University of Missouri. "The idea is to detect functional decline or early signs of illness, so we can identify problems when they are very small and proactively address them before they become catastrophic. That way, mom won't have to leave her home."
